I got the last one, since it was only $13. I also got the matching casters for a few bucks. It isn't extremely sturdy. The velcro holding the bag to the frame sometimes comes loose under heavy loads, and once one of the caster axles bent. But it was easy to bend back, and neither is a big problem.

If you live in a house and have a yard cart for that reason, you could use it as a laundry cart and shopping cart. (You'd need to wash it out with a hose or put your laundry bag in a black plastic garbage bag, to protect it from dirt.) (But, if you live in a house, you probably have a washing machine.) Anyway, here's a link to Suncast's wonderful $31 yard cart:

A cool tool can be any book, gadget, software, video, map, hardware, material, or website that is tried and true. All reviews on this site are written by readers who have actually used the tool and others like it. Items can be either old or new as long as they are wonderful. We post things we like and ignore the rest. Suggestions for tools much better than what is recommended here are always wanted.
